I've been testing stuff server side, and it seems that luminator tile entities occasionally error, and breaking or removing them by any means causes infinite luminators to spawn from the location of the tile entity, until you place a luminator back in it's place. It seems to only affect a chunk, when it happens, rather than everything on the power net.
Only way I found to remove them was forcing a crash by placing ultra-low-current cable in the space the luminator used to occupy.

yeah luminators are done horribly... I will change them so that they work better... But the next update is at least 1 month away so keep that in mind...

No worries, just didn't any an existing bug report.

i think i will also add multipart kinda like cables that supports lights on the same block...
they will not support FMP

If you want fmp cables I've done it

@modmuss50 its about making Plugs for wires that you can then have lamps on so that you do not need to have a seperate block... And no FMP support as long it is so buggy....

ah, no I cannot do that, was thinking of something else. And FMP does have its issues.

I fully endorse the idea of luminators occupying cable space, or socket cables.

Fixed & Improved
